Culture is the generalized term for the variation of characteristics that shape human identity. Culture is can be determined and explained in many perspectives. Ecological, evolutionary, conflict and symbolic interactionist perspectives of cultural are the four overall types of cultural variations that encompass culture in its most authentic way. The ecological variation of cultures can be best explained by the term Cultural Ecology. The North American Community for Cultural Ecology States, “Cultural ecology is, simply, the study of how humans adapt to social and environmental factors in order to survive and prosper. There are certain cultures that would have long died out if they hadn’t adapted to the physical landscape. Those adaption have become synonymous with those cultures and have very much become ingrained as the way of life. That, in short, is the entire concept of cultural ecology.” To explain that in a more simplistic way an example of cultural ecology would be like the relationship between animals and humans in the same environment for example in Tibet the people there have adapted to living with their wildlife like yaks. The yak lives in mountainous areas around Tibet, the yak like many other animals are crucial to Tibetan culture. Yaks provide meat, milk, hides, transportation for the people of Tibet, which are all thing that are building blocks of cultural ecology. The next perspective of cultural variations is cultural evolution. Cultural evolution can be defined as the theories of evolution like adaptation and darwinism are transmit cultural changes though cultural variations like language, customs, beliefs, knowledge, and so on. Tim Lewens wrote that, “Darwin described biological/genetic evolution as comprising three key components––variation, competition (or selection), and inheritance––cultural change also comprises these same phenomena.” Cultural evolution can be view as many thing for example, fads, sayings, or beliefs also undergo a “natural selection” of a sort by having to be continually reproduced or else they are forgotten. When it come to the theory of cultural conflict that refers to, people within culture feeling disempowered, unequal, or a power imbalance by society, the media, or even people within that culture or from another. More frequently than not you’ll find cultural conflict within multicultural communities or anywhere there is a difference in norms. Some of the biggest cultural conflict could be boiled down to race,religion, social and economics status, and gender, all being different variations that make up culture.
